Adhesive-Lined Semi-Rigid Polyolefin Heat Shrinkable Tubing -4:1

This versatile, exceptionally durable H421 adhesive-lined semi-rigid polyolefin heat shrinkable tubing offers an outstanding, highly reliable heat shrink tube solution perfect for use in a vast assortment of electrical cable and wire protection applications.

When H421 heat shrinkable sleeve is heated in excess of 121°C (250°F), it immediately shrinks to a skin tight fit around its internal contents, which then forces the melted adhesive lining to rapidly flow over and cover the underlying substrate. Upon cooling, the heat shrinkable tubing adhesive quickly solidifies, forming a permanent, non-drying, flexible and water resistant protective barrier against even the harshest of environmental factors.

H421 adhesive-lined polyolefin heat shrinkable tube has a 4:1 shrink ratio, meaning when it is freely recovered, the heat shrinkable sleeving will shrink down to 25% of its original diameter. Choose from a wide range of convenient sizes to meet the specific needs of your projects.
